A tool adaptor includes a body, a sleeve slidably mounted around the body, an elastic member abutting against the body and the sleeve, and an engaging ball. The body has a connecting hole and an engaging hole. The sleeve has a pressing portion. The engaging ball is movably disposed in the engaging hole and selectively pressed by the pressing portion to enter the connecting hole and to engage with an engaging groove a tool. A size of the at least one engaging ball is configured such that when the at least one engaging ball enters the connecting hole, a clearance is formed between an outer periphery of the engaging ball and a groove bottom face of the engaging groove.

A surgical device includes an adapter assembly that selectively interconnects a loading unit and a device housing. The adapter assembly includes a drive converter assembly for interconnecting a rotatable drive shaft and an axially translatable drive member of the loading unit. The drive converter assembly converts and transmits a rotation of the rotatable drive shaft to an axial translation of the axially translatable drive member of the loading unit. The drive converter assembly includes a drive element, a drive nut, and a distal drive member. The drive element defines a longitudinal axis. The drive nut is disposed about the longitudinal axis, and the distal drive member is disposed along the longitudinal axis.

Devices, systems and methods for holding devices, including tool holders and/or associated apparatus, that can be attached to various driving mechanisms. Various embodiments can include one or more canted, or slanted, coil springs that are capable of forming to various shapes by the application of a controlled force.

An apparatus and method for quick release of a spinner head assembly of a cotton candy machine. The spinner head is snap-fit to the rotational output shaft of the motor of the cotton candy machine to prevent longitudinal separation between the two during operation. Intermeshing portions between the spinner head and the output shaft are configured to translate rotational torque between the two and thus translate rotational torque of the output shaft of the motor to the spinner head. Quick release of the head is possible by pulling on the head along the rotational axis of the output shaft to overcome the snap-fit. This allows longitudinal separation of the spinner head and disengages the intermeshing portions for complete removal of the head. Reattachment is possible by snap-fitting connection between head and output shaft.

A driving adapter which is configured to be applied to a driving head of a rotary tool is provided. The driving adapter includes: a main body, including a socket portion, an insertion portion connected with the socket portion and a projection connected with the insertion portion in an axial direction, the socket portion including a connection hole which is quadrangular and extends along the axial direction, the insertion portion being a quadrangular post and extending along the axial direction, a diametric dimension of the insertion portion being different from a diametric dimension of the connection hole, the projection including an annular groove around the axial direction; an elastic retainer, being non-closed, disposed within and around the annular groove; and a cushion, disposed within the annular groove, being radially abuttable against and between the projection and the elastic retainer.
